This tip came from my friend Nathen. He hasn’t tried it yet, but it sounds cool. It comes from Prescription for Nutritional Healing:
“If you suspect that you are allergic to a specific food, a simple test can help you determine if you are correct. By recording your pulse rate after consuming the food in question, you can reveal if you are having an allergic reaction. Using a watch with a second hand, sit down and relax for a few minutes. When completely relaxed, take your pulse at the wrist . Count the number of beats in a sixty-second period. A normal pulse reading is between 52 and 70 beats per minute. After taking your pulse, consume the food that you are testing for an allergic reaction. Wait fifteen to twenty minutes and take your pulse again. If your pulse rate has increased more than ten beats per minute, omit this food from your diet for one month, and then retest yourself.
“For the purposes of this test, it is best to use the purest form of the suspect food available. For example, if you are testing yourself for an allergy to wheat, it is better to use a bit of plain cream of wheat cereal than to use wheat bread, which contains other ingredients besides wheat. This way you will know that whatever reaction you observe (or fail to observe), it is the wheat that is responsible.”
